= x + 16° + x + 3° =5x - 8°[ Sum of two interior angles is equal to the exterior angle]

or, 2x + 19 = 5x - 8

or, 19 + 8 = 5x - 2x

or, 27 = 3x

or, x = 27/3

☆ x= 9

Step-by-step explanation:

2. An electric fan has a resistance of 3.0 kN and a voltage rating of 220 volts. What
is the current needed to operate the electric fan?
Given:
Resistance (R)
ka x (1000/1 kg) =
volts
Voltage (V)
Required: Current (1)
Formula:
voltage
resistance
Solution:
V-IR
Answer:
Current =
A, the current needed to operate
the electric fan

Answers

Answer: 73.33A

Step-by-step explanation:

Resistance (R)= 3.0 kN

Voltage (V)= 220 volts

Current (I)= Unknown

The formula to calculate the current will be:

Current = Voltage / Resistance

Current = 220 / 3.0

Current = 73.33 A

Therefore, the current needed to operate the electric fan is 73.33.

Store A charges $1,200 for repairs with a 6 percent sales tax. Store B charges $1,350 with a 7 percent sales tax. Explain how you would determine the amount of money saved by using Store A instead of Store B?

Answers

Step-by-step explanation:

Store A:

6% of 1,200 is 72

72 + 1,200 = 1,272

Thus, store A has a total of 1,272

Store B:

7% of 1,350 is 94.5

94.5 + 1,350 = 1444.5

Thus, Store B has a total of 1444.5

1444.5 - 1,272 = 172.5

Thus, Store A is cheaper.

Answer:

sales tax- rate×original amount

A- 6/100(1200)=72

B- 7/100(1350)=94.5

Use intercepts to graph the line described by the equation 2x − 2y = 8.

Answers

So what you wanna do is graph a point at (0, -4) because the y intercept is -5 after you turn this into y intercept form.

Then what you have to do is graph the slope -1 so from the pint you just graph go down one and left one and keep on doing that until you reach the x axis.

The point which is on the x axis is the x intercept

Pls mark brainleist

Answer:

y = x + 4

Step-by-step explanation:

Slope intercept : 2x - 2y = 8 = 2x 2x = 8 + 2y = 2x = 8 +2y = 2x-8 =2y is the sae as 2y = 2x -8 divide everything by 2 = 2x / 2 - 8/2 = 2y/2 = y = x-4
